Regret

There is one instance in my recent memory I wish I had behaved differently.

Not too long ago I was doing namaz in public the way I've done so many times before.  This time was different.  Someone confronted me when I was doing namaz.  I wasn't scared at all.  It wasn't confrontational, but the other person was definitely adversarial.  I was civil and nice enough and I even said, "have a great day" at the end of our interaction.  I regret not being outwardly nicer.  I have thought about what I regret and what I still think about before.  In my head, I was nice, but he didn't know that.  He could have easily interpreted what I thought was pleasant as me being sarcastic when I said, "have a great day".  Mostly, I regret not taking an opportunity to have a good interaction and possibly brighten someone's day.

Taher, learn from this.  It's not enough to think it.  Do it and make it clear.
